Main report with lots of subreports

Question

I have sevral sub reports that pull information from two different databases, Is there a way to put all the subreports on one main report? The main report would only have parameter data, I'm using Crystal Reports XI release 2.

Answer 1

Hi,
That is possible (with certain constraints):
1.you may create each rpt one by one and save it as individual reports first.
2.later,you may create one main rpt and add each rpt file to this main by selecting the "choose an existing report" option in the Insert Subreport dialogue box.
3..you may do so by creating report footers(a,b,c,d and so on) in the main rpt and place each sub rpt one by one.
4.finally,all the required parameters may be created in the main rpt and they can be linked to the desired database field/parameter in the sub rpt.
Constraints:
1.since the databases are different so you will have to choose the database of your main rpt carefully.
2.the linking pattern of the main rpt parameter and sub rpt parameter will have to checked for the compatability(as in,whether the parameter/field are common in both,main and sub)
3.if there are any calculations within the sub rpt's and main or within sub rpt's themselves,then the shared variable values need to be checked for their correctness.
4.In this case(with reference to point 3 above) the physical placement of the sub rpt's (in the main) is crucial.
5.for e.g. if the calculation of a shared variable (say x) is happening in subreport A which is placed in report footer b(of main) then this variable may not fetch correct value if used in subreport B placed in report footer a.
6.That means,the variable value should be calculated in a section above than where it is being used.
